Dardanelles — the narrow strait between mainland Turkey in Asia and the peninsula of Gallipoli in Europe. The British and French considered it of strategic importance in securing a southern "warm" sea-route to resupply Russia. The first Allied landings in what became the Gallipoli Campaign had occurred on 25 April 1915 (that is, ten days before) at Cape Helles and Anzac Cove.

John George Mulvany, "Cottage Interior", c.1828 – flitches of bacon hanging from the rafters

bacon and cabbage — traditional Irish dish. The playwright John B. Keane wrote temptingly of Irish bacon: "Lest the wrong impression be given, let me say at once that the type of bacon I have in mind is homecured. It has been hanging from the ceiling for months, and when you cut a chunk from it there is the faintest of golden tinges about its attractive shapeliness. When this type of bacon is boiling with its old colleague, white cabbage, there is a gurgle from the pot that would tear the heart out of a hungry man." – John B. Keane, Strong Tea, 1963.

Stupefying Gases — 2nd Ypres marked the first extensive use of chlorine gas on the Western Front.

no mention of the Dubs — 2nd battalion RDF suffered heavy losses at Ypres. On 24 May a German gas attack effectively disintegrated the battalion as a fighting unit. (("Of 666 men, only one officer and 20 other ranks 'retired' to headquarters" – RDF Association.))

juldy — haste. A rendering of ((jildi: "haste, as in phrases 'on the jildi', in a hurry, and 'to do or move a jildi'" military slang, originally Anglo-Indian – OED.)) ((jildi!: "look sharp!" – Partridge HS.))

catch on to himself — ? come to an understanding of what he is about. ((catch on: "to understand; to grasp in meaning" colloquial – Farmer 1904.)) ((catch oneself on: "come to a realisation of something, adopt a normal view" – Slanguage.))
